As early the 200s AD, Kongming lanterns, (which essentially were miniature lantern/hot air balloons) were used in China for military signaling. However, the first manned hot air balloon flight (which was tethered to the ground), was done by Joseph-Michel and Jacques-Etienne Montgolfier in Annonay, France on October 19, 1783. The first untethered hot air balloon flight was done by the same brothers, in the same town, on November 21 of the same year.

How do they launch a hot air balloon?
To launch a hot air balloon, the pilot first inflates the balloon with a large fan to fill it with cold air. Then, a burner is used to heat the air inside the balloon until it becomes hot and the balloon starts to rise. Once it is fully inflated and upright, the passengers can board and the balloon will take off.
Why does a hot air balloon need flame in order to take off?
A hot air balloon needs a flame to heat the air inside the balloon, making it less dense than the surrounding air. This temperature difference creates lift, allowing the balloon to float upwards. Without the flame, the air inside the balloon would cool down and the balloon would descend.
Is it illegal to build a hot air balloon in your backyard?
If you have children, it should be illegal to have a balloon ready to jump into and take off.
What is compressed air propullsion?
The easiest way to describe compressed air propulsion: Blow air into a ballon (compress the air) then release the balloon. The balloon will take off (propulsion) due to the compressed air within.
What first the hot air balloon called?
On the 19th September 1783 Pilatre De Rozier, a scientist, launched the first hot air balloon called 'Aerostat Reveillon'
Why does an air balloon float?
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
Why Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
How do you get off a hot air balloon?
You climb out when the balloon lands on the ground and the basket is secure.
Why does a hot air balloon get off the ground?
A hot air balloon rises because the air inside the balloon is heated, making it less dense than the surrounding cooler air. This temperature difference creates a buoyant force that lifts the balloon off the ground.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.
Why did they call it the hot air balloon?
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
